is thrown.
Otherwise the complete resultMap is returned as the Message
payload.
Important Note: Several databases such as H2 are not fully supported.
The H2 database, for example, does not fully support the CallableStatement
semantics and when executing function calls against H2, a result list is
returned rather than a single value.
Therefore, even if you set expectSingleResult = true, you may end up with
a collection being returned.expectSingleResult
- true if a single result is expected.
